Description

Technical Field

[0001] This utility model relates to the field of tension detection technology for power lines, and more specifically, to a tension monitoring device for power transmission lines. Background Technology

[0002] During wire conveying, the wire is typically propelled forward by a conveyor roller. During this process, the cable needs to maintain a certain tension. Currently, most wire conveying devices provide tension by winding the cable around a tension wheel. The simplest method is to directly place a counterweight below the tension wheel, using the weight of the counterweight to provide tension.

[0003] Among them, the patent with announcement number CN212374609U discloses a wire tension buffer frame, including a support frame, at least two winding wheels on the support frame, a force wheel on the support frame, the tension wheel is connected to the support frame through a swing rod, the swing rod is hinged to the support frame through a transmission shaft, the transmission shaft is connected to a drive mechanism, a force sensor is also provided on the support frame, the drive mechanism, the tension sensor are connected to a controller, and the controller controls the drive mechanism to drive the transmission shaft to rotate.

[0004] This structure, belonging to the category of wire tension buffers, can monitor the tension of the wire in real time through a tension sensor during use. At the same time, the tension of the cable can be controlled by controlling the swing angle of the tension wheel through a drive mechanism. However, this structure is not easy to limit the wire during use, which can cause the wire to fall off when it twists, resulting in inaccurate tension detection. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a tension monitoring device for transmission lines, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a tension monitoring device for transmission lines, including a base, on which a supporting monitoring component is provided;

[0007] The support monitoring component includes a guide cylinder disposed on the top of the base, a support plate disposed at the top of the guide cylinder, and a reinforcing support pad for supporting the wire embedded in the middle of the support plate.

[0008] A pressure rod is slidably connected to the middle of the guide cylinder. A tension sensor for tension detection is provided at the bottom of the pressure rod. A limiting cavity is formed between the outer side of the support plate and the reinforcing support pad. Several anti-slip pads for anti-slip are fixedly provided on the outer side of the reinforcing support pad.

[0009] As can be seen, in the above technical solution, the cable is positioned by the limiting cavity, while the support plate can block the cable to prevent it from falling out of the limiting cavity. At the same time, the anti-slip pad on the outside of the reinforced support plate increases the friction between the cable and the reinforced support plate.

[0010] Optionally, in one possible implementation, a horizontal shaft is rotatably connected to the middle of the reinforcing support pad, the horizontal shaft is inserted into the top of the pressure rod, a slip ring is bolted to the outside of the pressure rod, the slip ring is located in the middle of the guide cylinder and is slidably connected to the guide cylinder, a spring is provided at the bottom of the slip ring, the spring is sleeved on the outside of the pressure rod and the bottom of the spring extends to the tension sensor, a guide groove is provided through the outside of the pressure rod, a guide rod is slidably connected in the guide groove, and the guide rod is inserted into the top of the guide cylinder;

[0011] As can be seen, in the above technical solution, the support plate drives the pressure rod to move the slip ring within the guide cylinder, thereby applying pressure to the spring while the pressure rod is moving. This pressure is then transmitted to the tension sensor, which detects the pressure and thus the cable tension. The support plate effectively prevents the cable from falling off, ensuring monitoring accuracy. The guide groove and guide rod guide and limit the displacement of the pressure rod, ensuring its stability and tension detection accuracy.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] By setting up a support monitoring component, the overall design is simple and the structure is reasonable. Through the corresponding cooperation of each structure, the cable is positioned through the limiting cavity, while the support plate can block the cable and prevent the cable from falling out of the limiting cavity. At the same time, the anti-slip pad on the outside of the reinforced support pad increases the friction between the cable and the reinforced support pad.

[0014] Furthermore, the slip ring moves within the guide cylinder, which in turn causes the pressure rod to move while applying pressure to the spring. This pressure is then transmitted to the tension sensor, which detects the pressure and thus the cable tension. The support plate effectively prevents the cable from falling off, ensuring monitoring accuracy. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As attached Figure 1 - Figure 4 The tension monitoring device for a power transmission line shown uses a support monitoring component on the base 1. The support plate 3 can block the cable and prevent it from falling out of the limiting cavity. At the same time, the anti-slip pad 5 on the outside of the reinforcing support plate 4 increases the friction between the cable and the reinforcing support plate 4. The slip ring 8 moves in the guide cylinder 2, which causes the pressure rod 7 to move and apply pressure to the spring 9. The pressure is then transmitted to the tension sensor 10. The tension sensor 10 detects the pressure and thus detects the cable tension. The support plate 3 can effectively prevent the cable from falling out and ensure monitoring accuracy. The specific structure of the component is as follows.

[0023] The support monitoring component includes a guide cylinder 2 set on the top of the base 1, a support plate 3 set at the top of the guide cylinder 2, and a reinforcing support pad 4 for supporting the wire embedded in the middle of the support plate 3.

[0024] A pressure rod 7 is slidably connected to the middle of the guide cylinder 2. A tension sensor 10 for tension detection is provided at the bottom of the pressure rod 7. A limiting cavity is formed between the outer side of the support plate 3 and the reinforcing support pad 4. Several anti-slip pads 5 for anti-slip are fixedly provided on the outer side of the reinforcing support pad 4.

[0025] A horizontal shaft 6 is rotatably connected to the middle of the reinforcing support pad 4. The horizontal shaft 6 is inserted into the top of the pressure rod 7. A slip ring 8 is installed on the outside of the pressure rod 7 by bolts. The slip ring 8 is located in the middle of the guide cylinder 2 and is slidably connected to the guide cylinder 2. A spring 9 is provided at the bottom of the slip ring 8. The spring 9 is sleeved on the outside of the pressure rod 7, and the bottom of the spring 9 extends to the tension sensor 10. A guide groove 11 is opened through the outside of the pressure rod 7. A guide rod 12 is slidably connected in the guide groove 11 and is inserted into the top of the guide cylinder 2.

[0026] When using the above structure, the staff will install the device on the cable support frame so that the cable can be distributed in the limiting cavity. The limiting cavity will position the cable, while the support plate 3 can block the cable to prevent it from falling out of the limiting cavity. At the same time, the anti-slip pad 5 on the outside of the reinforcing support pad 4 will increase the friction between the cable and the reinforcing support pad 4.

[0027] Furthermore, when the cable bends, the reinforcing support plate 4 and the support plate 3 are driven by the force to move the pressure rod 7, which in turn causes the slip ring 8 to move within the guide cylinder 2. This displacement of the pressure rod 7 applies pressure to the spring 9, allowing the pressure to be transmitted to the tension sensor 10. The tension sensor 10 detects the pressure, thereby detecting the cable tension. The support plate 3 effectively prevents the cable from falling off, ensuring monitoring accuracy. At the same time, the guide groove 11 and the guide rod 12 guide and limit the displacement of the pressure rod 7, ensuring the stability of the pressure rod 7 during displacement and ensuring the accuracy of tension detection.

[0028] Unlike existing technologies, this application discloses a tension monitoring device for power transmission lines. The support plate 3 can block the cable and prevent it from falling out of the limiting cavity. At the same time, the anti-slip pad 5 on the outside of the reinforcing support plate 4 increases the friction between the cable and the reinforcing support plate 4. The slip ring 8 moves within the guide cylinder 2, which in turn causes the pressure rod 7 to move and apply pressure to the spring 9. This pressure is then transmitted to the tension sensor 10, which detects the pressure and thus the tension of the cable. The support plate 3 can effectively prevent the cable from falling out and ensure monitoring accuracy.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
